Büsingen am Hochrhein, often known simply as Büsingen, is a German municipality (7.62 km2 [2.94 sq mi]) in the south of Baden-Württemberg with a population of about 1,548 inhabitants. It is an exclave of Germany and Baden-Württemberg, and an enclave of Switzerland, entirely surrounded by the Swiss cantons of Schaffhausen, Zürich, and Thurgau. It is separated from the rest of Germany by a narrow strip of land containing the Swiss village of Dörflingen. Büsingen is approximately 5 km (3.1 mi) from the town of Schaffhausen and 3 km (1.8 mi) from Dörflingen, the nearest village. Its status as an exclave dates to before the formation of the modern German and Swiss states, having previously been a detached part of Further Austria, the Kingdom of Württemberg and the Grand Duchy of Baden.
